分配在 rspec-rails 中做什么

RSpec Rails 中的分配：简化测试套件管理

ruby
RSpec.describe PostsController, type: :controller do
  describe "GET #show" do
    it "assigns the requested post to @post" do
      post = Post.create(title: "Sample Post", body: "This is the content of the post.")
      get :show, params: { id: post.id }
      expect(assigns(:post)).to eq(post)
    end
    it "renders the :show template" do
      post = Post.create(title: "Sample Post", body: "This is the content of the post.")
      get :show, params: { id: post.id }
      expect(response).to render_template(:show)
    end
  end
end
